i have vibration and its bugging me....
when will it be ready? is there one in the market already?

I got the chrome one below.

Just out of interest, does anyone know if more solid engine mounts or just inserts are made for the TSX?

Can someone explain what the engine mount electronic control actually does and how?

Since the engine is the heaviest concentrated component in a vehicle, and the source of significant vibration, the mounting system that supports it has a profound effect on interior noise levels, handling and overall driving characteristics. Isolating the engine from the body with "soft" mounts can make for good NVH characteristics, but wreak havoc on handling and driveline performance as the engine moves on its mounts. Conversely, locking the engine in place (like in a racing machine) is the best from a handling standpoint, but guarantees unbearable NVH performance. For the TSX, neither extreme was appropriate. The TSX uses a carefully orchestrated system of six mounts to combine impressively high levels of isolation with stable engine placement for precise handling.
Two mounts are placed below the TSX engine's center of gravity, and attach the engine to the front subframe, which itself is isolated from the car's body by bolted rubber mounts. The forward-most of these two "center of gravity" engine mounts is an electronically controlled hydraulic unit with variable dual-mode stiffness. It switches between a setting optimized for damping vibration at idle, and another firmer setting for higher speeds and rougher roads. The rear most of the center of gravity mounts is a non-adjusting hydraulic unit.
To keep the engine properly positioned during severe maneuvering, another electronically controlled dual-mode mount is placed high on the right side of the engine to tie it to the body structure. Finally, to carry the weight of the transmission and limit powertrain movement, a series of three mounts position the transmission.

ETD Internal
I just received my short ETD today and it came with one extra set of bushings. I got curious and decided to take it apart as well as my long ETD to see how it works.
It turns out the unit is not a gas shock. It's a friction unit that utilizes bushings. It consists of a nylon bushing which pushes against two additional bushings causes them to expand and compress inside the ETD body. The preload sets the initial stiffness. The short version has the option of poly bushings or rubber bushings (interchangeable). The NRG is a really nice piece.

BTW, which car does the NRG ETD that you bought fit on?

The Cusco/Spoon compatible bracket is done! It's being painted right now but here is a pics of the shock tower bracket. The fitment is very good and clears everything. However, like I mentioned before, the stock bar has to come off. The engine mount bracket is the same.
